Limit the Liquids
On the road, the best choice for a beverage is simply water. For one thing, it's cheap -- really cheap if you fill water bottles from the tap at home. If spilled, water won't make seats and door handles sticky. Kids aren't as likely to overindulge on water as they are with sweet soda or juice. They'll drink only as much as they need to quench their thirst. This means you won't be hitting the road with a bunch of kids hopped up on sugary beverages. Another bonus: Less liquid means fewer time-consuming bathroom breaks. If the kids won't drink plain water, add a bit of juice to give it some flavor. If juice is a must, don't forget the hard-sided holders to contain those flimsy boxes -- they're a disaster just waiting to happen.
